When Tesla makes a move, even casual technology observers move with them. Elon Musk’s built his corporation into the most legitimate form of clickbait: if Tesla’s in the news, it’s always worth checking out why. On April 30, 2015, the company announced its latest breakthrough: the Powerwall home battery. This battery, according to the company’s website, this products aims to offer “independence from the utility grid and the security of an emergency backup.” For the aforementioned casual tech observers, this is likely the first you’ve heard about major home batteries; but for those in the know, they’re asking the right question - is Tesla’s Powerall the best of these products?
LG Chem, a competing battery manufacturer who commands the third-greatest sales of EV batteries in 2014, looks to upstage Tesla’s release with a home battery storage unit of their own. Coinciding near Tesla’s own announcement, LG Chem announced a similar product made with Eguana Technologies called the AC Battery. Its usage purposes span both commercial and industrial, making it unabashedly similar to what Tesla’s putting out with the Powerwall. In evaluating the two competing products, both of which are eyeing Summer 2015 releases, looking at the details will truly see which of the two comes out on top.
Tesla comes with 7kWh and 10kWh models, while data puts LG Chem’s basic capacity at 6.4kWh. This is one singular metric, and cost and other factors are sure to sway customers towards one of the two products, but as it stands, the comparable capacity with Tesla’s basic 7kWh model makes LG Chem’s desire to steal Tesla’s thunder more legitimate than one may have first imagined. For all of those salivating at this talk of advanced batteries and kWh measurements, being an engineer intimately involved with these products is in close reach.
Online programs -- like Syracuse University’s electrical engineering courses online -- prepare students with a comprehensive education taken at one of the nation’s top universities stretched over an exciting 20-month period of time. Intensive courses that train students in electromagnetic fields, electronic circuits, and antennas, among other course offerings, prepare those embarking on this journey to command a great depth in the electrical engineering field and qualifying them to work for lucrative industries.
LG Chem might not have definitively stolen Tesla’s thunder yet, but they’re closer than any company has come before. Regardless of your affiliations, a M.S. in electrical engineering helps graduates to work for either company, taking Tesla’s thunder to higher decibels, or deafening them with LG Chem’s efforts. Either way, the home battery wars are just starting, and we’re going to come out far more efficient because of them.
